Menene amfanin flotation?

Ruwa, wanda kuma aka sani da flotation froth, wata dabara ce ta sarrafa ma'adinai wacce ke raba ma'adanai masu mahimmanci daga ma'adinan gangue a ma'auni mai ƙarfi-gas ta hanyar haɓaka bambance-bambance a cikin abubuwan saman ma'adanai daban-daban. Ana kuma kiransa da "rarrabuwar fuska." Duk wani tsari wanda kai tsaye ko a kaikaice yana amfani da musaya na zamani don raba barbashi na ma'adinai dangane da bambance-bambancen kaddarorin su na fuska ana kiransa flotation.

Ma'adinai surface Properties koma zuwa jiki da sinadaran halaye na ma'adinai barbashi saman, kamar surface wettability, surface lantarki Properties, iri sinadaran bond a kan surface zarra, jikewa, da kuma reactivity. Barbashi ma'adinai daban-daban suna nuna kaddarorin sararin samaniya, kuma ta hanyar yin amfani da waɗannan bambance-bambance tare da taimakon mu'amalar lokaci, ana iya samun rabuwar ma'adinai da haɓakawa. Sabili da haka, tsarin flotation ya ƙunshi hulɗar gas, ruwa, da matakai masu ƙarfi a wurin sadarwa.

Ana iya canza kaddarorin ma'adinai ta hanyar sa baki na wucin gadi don haɓaka bambance-bambance tsakanin ma'adanai masu mahimmanci da ma'adinan gangue, don haka sauƙaƙe rabuwarsu. A flotation, flotation reagents yawanci amfani da artificially gyara ma'adinai surface Properties, inganta bambance-bambance tsakanin ma'adanai, da kuma karuwa ko rage hydrophobicity na ma'adinai saman. Wannan yana ba da damar daidaitawa da sarrafa halayen hawan ruwa na ma'adinai don cimma sakamako mafi kyau na rabuwa. Saboda haka, aikace-aikace da haɓaka fasahar flotation suna da alaƙa da amfani da reagents na flotation.
